The former France, Arsenal and Barcelona striker ran into the box during a stoppage of play in the 93rd minute and appeared to intentionally headbutt Kansas City's Kei Kamara.
The two players went down and the incident triggered a confrontation between the teams. New York lost the game 2-0.
Henry, who has scored 13 goals this season, will serve the suspension when his team visit the New England Revolution on Saturday.
